Summary
Anaphylaxis is in most cases an IgE-dependent immunologic reaction. Mast cells are activated and release several mediators. Recent data about possible triggers of anaphylaxis indicate a clear age-dependency. The most frequent triggers of anaphylaxis in children are foods; in adults venom and drugs predominate. In 2006 an anaphylaxis registry was established in German-speaking countries. In the registry the triggers, circumstances, and treatment measures are collected from patients with anaphylaxis. However, the registry cannot supply epidemiological data like prevalence or incidence rates since the registration of cases is based on collaboration with allergy centers only. Similarly, other approaches to obtain data on the epidemiology of anaphylaxis are problematic given that allergic reactions of varying severity are covered by a number of codes in the ICD-10.
Research in the field of anaphylaxis is focused on the identification of risk factors. Several data indicate the relevance of co-factors and augmentation factors in well-defined patient groups. Among these factors physical activity, infection, alcohol and additives are relevant. In the future a unique coding system with a subtype analysis regarding the triggers and severity should help to provide data on the epidemiology of anaphylaxis. Furthermore the mechanisms of co-factors and identification of biomarkers for risk assessment are important research areas for the future.
